The GCF is the largest number that can divide two or more numbers without leaving any remainder. GCF is used to share the items equally, to group or arrange items, and schedule events. In this topic, we will learn about the GCF of 36 and 60.

What is the GCF of 36 and 60?

The greatest common factor of 36 and 60 is 12. The largest divisor of two or more numbers is called the GCF of the numbers.

If two numbers are co-prime, they have no common factors other than 1, so their GCF is 1. The GCF of two numbers cannot be negative because divisors are always positive.

How to find the GCF of 36 and 60?

To find the GCF of 36 and 60, a few methods are described below :

  1. Listing Factors
  2. Prime Factorization
  3. Long Division Method / by Euclidean Algorithm

GCF of 36 and 60 by Using Listing of Factors

Steps to find the GCF of 36 and 60 using the listing of factors:

Step 1: Firstly, list the factors of each number Factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18, 36. Factors of 60 = 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60.

Step 2: Now, identify the common factors of them Common factors of 36 and 60: 1, 2, 3, 4, 6, 12.

Step 3: Choose the largest factor The largest factor that both numbers have is 12. The GCF of 36 and 60 is 12.

GCF of 36 and 60 Using Prime Factorization

To find the GCF of 36 and 60 using the Prime Factorization Method, follow these steps:

Step 1: Find the prime factors of each number Prime Factors of 36: 36 = 2 x 2 x 3 x 3 = 2² x 3²

Prime Factors of 60: 60 = 2 x 2 x 3 x 5 = 2² x 3 x 5

Step 2: Now, identify the common prime factors The common prime factors are: 2 x 2 x 3 = 2² x 3

Step 3: Multiply the common prime factors 2² x 3 = 4 x 3 = 12. The Greatest Common Factor of 36 and 60 is 12.

GCF of 36 and 60 Using Division Method or Euclidean Algorithm Method

Find the GCF of 36 and 60 using the division method or Euclidean Algorithm Method. Follow these steps:

Step 1: First, divide the larger number by the smaller number Here, divide 60 by 36 60 ÷ 36 = 1 (quotient), The remainder is calculated as 60 − (36×1) = 24 The remainder is 24, not zero, so continue the process

Step 2: Now divide the previous divisor (36) by the previous remainder (24) Divide 36 by 24 36 ÷ 24 = 1 (quotient), remainder = 36 − (24×1) = 12 The remainder is 12, not zero, so continue the process

Step 3: Now divide the previous divisor (24) by the previous remainder (12) Divide 24 by 12 24 ÷ 12 = 2 (quotient), remainder = 24 − (12×2) = 0

The remainder is zero, the divisor will become the GCF. The GCF of 36 and 60 is 12.

Common Mistakes and How to Avoid Them in GCF of 36 and 60

Finding the GCF of 36 and 60 looks simple, but students often make mistakes while calculating the GCF. Here are some common mistakes to be avoided by the students.

Problem 1

A teacher has 36 notebooks and 60 markers. She wants to group them into equal sets, with the largest number of items in each group. How many items will be in each group?

Okay, lets begin

We should find the GCF of 36 and 60 GCF of 36 and 60 2² x 3 = 4 x 3 = 12. There are 12 equal groups 36 ÷ 12 = 3 60 ÷ 12 = 5 There will be 12 groups, and each group gets 3 notebooks and 5 markers.

Explanation

As the GCF of 36 and 60 is 12, the teacher can make 12 groups. Now divide 36 and 60 by 12. Each group gets 3 notebooks and 5 markers.

Well explained 👍

Problem 2

A school has 36 red chairs and 60 blue chairs. They want to arrange them in rows with the same number of chairs in each row, using the largest possible number of chairs per row. How many chairs will be in each row?

Okay, lets begin

GCF of 36 and 60 2² x 3 = 4 × 3 = 12. So each row will have 12 chairs.

Explanation

There are 36 red and 60 blue chairs. To find the total number of chairs in each row, we should find the GCF of 36 and 60. There will be 12 chairs in each row.

Problem 3

A tailor has 36 meters of red fabric and 60 meters of blue fabric. She wants to cut both fabrics into pieces of equal length, using the longest possible length. What should be the length of each piece?

Okay, lets begin

For calculating the longest equal length, we have to calculate the GCF of 36 and 60 The GCF of 36 and 60 2² x 3 = 4 × 3 = 12. The fabric is 12 meters long.

Explanation

For calculating the longest length of the fabric first, we need to calculate the GCF of 36 and 60, which is 12. The length of each piece of fabric will be 12 meters.

Well explained 👍

Problem 4

A carpenter has two wooden planks, one 36 cm long and the other 60 cm long. He wants to cut them into the longest possible equal pieces, without any wood left over. What should be the length of each piece?

Okay, lets begin

The carpenter needs the longest piece of wood GCF of 36 and 60 2² x 3 = 4 × 3 = 12. The longest length of each piece is 12 cm.

Explanation

To find the longest length of each piece of the two wooden planks, 36 cm and 60 cm, respectively. We have to find the GCF of 36 and 60, which is 12 cm. The longest length of each piece is 12 cm.

Well explained 👍

Problem 5

If the GCF of 36 and ‘a’ is 12, and the LCM is 180. Find ‘a’.

Okay, lets begin

The value of ‘a’ is 60.

Explanation

GCF x LCM = product of the numbers 12 × 180 = 36 × a 2160 = 36a a = 2160 ÷ 36 = 60
